Given:
Length of room = 9 m
Breadth of room = 6 m
Width of carpet = 2 m
Rate of carpet = ₹ 350 per metre
Area of the floor = length × breadth
= 9 × 6 sq. m
= 54 sq. m
Area of carpet = Area of floor (since the carpet exactly covers the floor) = 54 sq. m
Length of carpet =
=
= 27 m
Cost of carpet = Length × Rate
= 27 × 350
= ₹ 9450
Hence, the cost of covering the floor with carpet is ₹ 9450.
